Coprolite with Toothed Jaw Fragment

Some of the best coprolites are tiny fragments, this most people wouldn't bother to pick up. This coprolite fragment wouldn't even cover the tip of a finger. The outer surface shows no hint at what was beautifully preserved inside. Among the bone inclusions is a tiny jaw with teeth. I haven't been able to identify the prey, but it is likely a fish or lissamphibian.
